Also a useful model for understanding the basis of increased lymphoid malignancies in immunodeficiencies as thymic lymphomas occurs in about 15% of mice.

Useful model for studying the relationship between immunity and disease, studies on engraftment of xenogenic cells and tissues and studying human severe combined immunodeficiency.

Macrophage activation and antigen presentation, NK cell activity and myeloid cell differentiation is normal.

A variable percentage (2-20%) of young adults develops low numbers of functional B and T-cells. SCID mice are homozygous (C.B-17/Icr Prkdcscid/scid) for the Prkdcscid allele, which has been mapped to the centromeric end of chromosome 16.

Although B and T-cells and pre-B and pre-T cells are absent early B and T-cells are present. 80 female and 80 male mice were obtained at weaning (birthdate +/- 3 days) from maximum barriers in both Bar Harbor and Sacramento facilities and weighed the same day each week until 16 weeks of age. Despite this leakiness C. JAX Mice Strain - NOD.CB17-Prkdc scid /J. The incidence of Ig will increase as the mice age.

Bone marrow lacks plasma cells and lymphocytes and skin lacks dendritic Thy-1 + epidermal cells. The C.B-17-scid does exhibit extremely low levels of Ig in 20 of the mice at 12 weeks of age. The splenocytes from CB17/SCID mice showed higher cytotoxicity than those from NOD/SCID mice, while the cytotoxicity of purified NK cells basically did not.Lymphoid organs consist of vascular connective tissue and macrophages and are devoid of lymphocytes. A comparison of a CB17 scid mouse model and the tetrazolium-dye assay using human haematological tumour cell lines Abstract Author information Additional. Localisation of human peripheral blood leukocytes after transfer to C.B-17 scid/scid mice.

Taconic continues to produce the C.B-17 scid model at the Excluded Flora health standard (US) and the Opportunist Free health standard (Europe). Homozygotes have little or no immunoglobulin in serum. CALL: 888.822.6642 + 45 70 23 04 05 (EUROPE) Taconic has ceased production of the C.B-17 scid at the Defined Flora health standard.Prkdc scid (autosomal recessive, protein kinase, DNA activated, catalytic polypeptide). Arose as a spontaneous autosomal recessive mutation in C.B-Igh-1 b (CB-17) congenic strain.Moreover, splenic cell suspensions derived from alpha-asialo GM1-treated SCID mice show lower cytotoxicity against the mouse NK-sensitive cell line YAC-1 and human EBV-LCL than splenocytes obtained from untreated SCID mice.Albino ( A/ A Tyrp1 b/ Tyrp1 b Tyr c/ Tyr c) C.B - 17 SCID nylon wool nonadherent spleen cells were sorted for 5E6 + and 5E6- subsets and were cultured for 10 days in IL - 2, as described above. We also demonstrate that SCID mice treated with alpha-asialo GM1 have reduction in the number of asialo GM1-expressing splenocytes. Furthermore, at any given dose of EBV-LCL inoculated, EBV-LPD developed earlier and induced lethality sooner in alpha-asialo GM1-treated animals. In the present study, we demonstrate that SCID mice treated with rabbit anti-asialo GM anti-serum (alpha-asialo GM1), for in vivo depletion of endogenous NK cell function, develop lethal Epstein-Barr virus (EBV)-induced lymphoproliferative disorders (EBV-LPD) at lower doses od inoculated EBV-transformed lymphoblastoid B cell lines (EBV-LCL) than untreated animals. Mouse NK cells express the surface glycolipid asialo GM1 and are implicated in the rejection of heterotransplanted cells. However, the development of functional NK cells is not affected by the scid mutation. Mice with severe combined immune deficiency (C.B-17 scid/scid ) lack functional B and T lymphocytes and are permissive for the growth of human xenografts. Administration of rabbit anti-asialo GM1 antiserum facilitates the development of human Epstein-Barr virus-induced lymphoproliferations in xenografted C.B-17 scid/scid mice. Serum immunoglobulin analysis did not detect IgG or IgM in NOG mice, unlike the findings in C.B-17-scid and NOD-scid mice. The congenic CB17 SCID mouse model is commonly used in tumor biology, xenograft research, transplantation and immunology studies.
